What is a flight table primarily used for?

A flight table is primarily used for calculating performance data such as takeoff and landing distance. This tool is vital for pilots and flight planners as it helps determine the necessary runway length required for safe aircraft operation under various weight and environmental conditions. By utilizing the flight table, pilots can ensure they have the correct performance metrics for different aircraft configurations, altitudes, and air temperatures, thus enabling safer takeoffs and landings.

Other options, while related to aviation, do not fully capture the primary function of a flight table. Tracking flight hours for pilots, logging passenger information, and monitoring weather reports are all important aspects of aviation operations but fall under different categories of flight management or record-keeping systems.
